MOLD CAP.

Application filed October 25, 1921. Serial No. 510,378.

To all whom it"mag concern:

Be it known that I, EDMOND H. NnILL, a citizen of the United States,residing at Austin, in the county of Travis and State of Texas, haveinvented new and useful Improvements in Mold Caps, of which thefollowing is a specification.

.My invention has reference to a casting 'mold for matrix setting andline casting machines, by means of which the casting slot can beaccurately'set to given fractions or typographical measuring units.

In the accompanying drawings Figure 1 is a front elevation of thecasting mold;

Figure 2 is a plan view looking toward the inner face of the mold cap.

Figure 8 is a plan view of the mold body.

Figure 4 is a side elevation of one of the end filler blocks.

Figure 5 is an end view thereof.

Figure 6 is a view 1 illustrating more clearly the taper at. the topedge of the filler block as well as the opening through which the.securing screw passes.

Figure 7 1s afragmentary elevation of the mold cap, illustrating thearrangement 01":

the slots for the quad.

Figure 8 is an end view of the mold cap illustrating the beveled frontedge to accommodate the screw driver in engaging lip of quad.

Figure 9 is an elevation of the quad.

Figure 10 is a view of the spacer block.

Figure 11 is a plan View thereof.

Figure 12 is a side elevation thereof.

As is well known in the art the ordinary casting mold is-composed of acap, a base, and two liners between the cap and base at the endsthereof. llhe cap is pressed down 011 the liner by three screws in themold wheel, one on each end of the cap and the other at the center. Inchanging the size or length of a mold, that is'the length of the slugthe mold is set to cast, it is necessary to loosen-all three of: thescrews, pull out the liners and replace them with others of the requiredsize and length. For instance, say the mold is set for an 8 point slug.18 ems long and it is desired to change it to a 10 point slug 13 ems inlength, the liners being both 8 points, one 0 ems and the other 12 ems,and, as the length of the mold on the inside is 30 ems, this leaves themold slot 18 cms in length and 8 points thick. To change to the abovemeasurements the three mold cap screws are loosened and the 8 pointliners are withdrawn, while a 10 point liner is arranged in one end ofthe mold and a 10 point liner 11 ems long is arranged in the other endof the mold. The cap is then pressed down on the liners by ad usting thescrews and the mold slot is 10 points thick and 13 ems'long. This iscomparatively an easy operation if there are sufficient liners on hand,but as machines are required to set almost every measure from f to 30ems on slugs of various sizes from 6 to 36 points.

an extent that it will not eject through the trimming knives.

YVith my improvement, the mold is constructed substantially similar tothat of the ordinary mold, the body 1 of the mold, at its upper edgebeing provided adjacent its end with the usual notch 2, and a cap 3being provided upon its under face, adjacent its ends with a pluralityof transversely arranged slots or notches i, 5 and 6 respec-' tively.Between theinner notchese the inner edge of the cap 3 is formed withtransverse depressions which define straight and angular walls and whichare indicated by the numeral 7.

Instead of employing liners in the usual manner between the confrontingfaces of the body cap, at the ends thereof, I make use of filler blocks8 respectively. These filler blocksare each in the nature of a flatplate and each has its under faces formed with a lug which is designedto be received in the not-ch 2, the outer ends of the filler blocksbeing in contacting engagement with the posts 10 on the ends of thebody 1. The upper face of the filler blockis provided with spacednotches 11 and 12 respectively, while the inner end of each filler blockis provided with an upstanding lug 13, the said lugs being disposed overthe notch t inthe cap 8. Each filler block has a prefer- ,ably reamedopening therethrough and through this opening there is passed a headedscrew 14 which enters a threaded opening in the body 1.

it will be noted that the lugs 15 and 16 provided by the depressions 11and 12 are disposed opposite the notches 5 and 6 in the SllOUil'ClGFSbetween the depressions at, 5 and 6 in accordance with the width desiredin the casting slot, it being understood that the lug 13 is neverentirely withdrawn from the notch 4, and also that the notch 4 is ofagreater depth than the notches 5 and 6.

It will thus be noted that the thickness of'the slug may be readilyadjusted by the operator,- and also that the operator can make suchadjustment without necessitating him leaving his seat, it being merelynecessary'to withdraw thequad from one of its mentioned positions andreinserting the same in another position. To facilitate this the outeror preferably upper corner of the quad is formed with a ledge or lip andalso the quad is beveled or arranged at an inclination. It add1t1on tothis the employment of the end mold cap screws may be dispensed with.The pressure from the central mold cap screw 'eitectively holds thequadsin effective engagement with the tiller blocks.

To regulate the slot so that slugs of desired lengths can be cast I makeuse of what I will term spacer blocks and which are indicated in thedrawings by the numeral 18. These spacer blocks are of a slze to bere'ceivedin the slot in the mold and as illustratedin Figure 10 of thedrawings, the

same may be provided with a plurality of teeth 20 to be received in thesubstantially V-shaped notches 7 in the inner face 01 the cap also, ifdesired, the spacer block may be provided with a single tooth. The teeth20 of the spacer block fit snugly in the notches 7 in the mold cap,and'hold the same positively in position, and of course, the spacebetween the filler block and the spacer block on the right hand side ofthe mold determines the length of the slot and consequently the lengthof the slug to be cast. To facilitate the insertion and withdrawal ofthe fillerblocl ts the same are, as illustrated in the drawingssubstantially beveled or wedge -shap'ed having their inner ends roundedand their outer edges formed with lips for engagement by a suitableinstrument suchas a screw driver, or if desired by the fingers oi theoperator.

The spacer blocks, it is to be noted'are of a similar construction, andare reversely arranged in position in the mold. No change is made in themold base and but few changes are necessitated in the mold cap inproviding the same with my improvement, while the element which I havere terred to as a quad is really in the nature of a key which is gof aninch long and 10 points square, with the exception of ends, one of whichis provided with a lip, and the other rounded or tapered to permit theready removal and insertion of the same.

It is also believed that the foregoing de scription, when taken inconnection with the drawings will fully set forth the construction andadvantages of the improve' ment to. those skilled in the art to whichsaid invention relates and that further detailed description will notbeneeessary. It

is, or course, to be understood that I am entitledito such changes fromthe showing and description as may be found necessary or desirable inthe manufacture thereof, such changes however, not departing from thescape of theappended claims.
